He's a botter, im not sure why the picture shows slark DK etc but if you actually watch both games and look at the heroes they're using, its Lich, Rhasta, Warlock, Jakiro and Necrolyte.

This is the burst lineup used to farm Jade tokens where they enter, throw down 2 mines and all their ults to hit the minimum required damage to token rewards. He is a botter who has written bots to use this burst strat, something has gone wrong with the script while he has been away and they've just been afk since then.
